It’s been over a month since I first made these plant-based burgers, and since then I’ve lost count of just how many times I’ve made them (it’s been a lot!). They’re juicy and easy and super satisfying, which is how they’ve won a spot in my dinner rotation.
Thick portobello mushroom caps (be sure to buy large ones!) are marinated and grilled until tender and lightly charred, then added on your favorite hamburger bun (which has already been swiped with pesto on both sides!) and layered with sweet and tender grilled red onion, roasted red pepper, and a small handful of spicy arugula.
